SIEECIFIGATION forming part of Letters Patent No. 552,038, dated December 24, 1895- Apjilication filed March 25, 1890.

To all ivhom it may concern Be it known that I, l\[0RTON G. BUNNELL,

cage, infthe county of Cook and State of Illinois, have invented a certain new and useful Improvement in Supplemental Conveyers for thefollowing is a specification.

My invention while applicable to various proved attachment to the construction of grading and ditching machine set. forth in Edwards, 'November 27, 1888, No. 393,467.

becomes at times desirable to deliver the plow than can be. attained with a'singlc'machine. p

The object of my invention is to overcome by side, and while butoneis used for plowing up thesoi-l the two machines can be used conjointly for conveying and delivering the, same from the plow to a point remote from that \vhereat the soil is plowed-up.

ditching machine provided with my improvement. Fig. 2 represents in elevation on a larger scale the conveyor hopper or receiver. Fig. 3 is a diagram illustrating the elevatingbottom of the hopper. Fig. 4. is a longitudinal section on avertieal plane through atportion or: the conveyor and also through the hopper. Fig. 5 represents a section taken through a portionof the hopper on a plane transverse to the length of the conveyor-belt, which lat ter is partially show Fig. (3 is a plan of the hopper and a portio of the conveyor, and shows the conveying-aprons, which form the bottom of the main conveying belt or apron. Fig. 7 is a section taken transversely through the machine, the plane of the section being through the elevating-convcyer.

. The machine re resented in Fi s. 1 and 7 P s Serial No. 345,271. No model.)

is generally similar to that described in the patent hereinbeforereferred to, and hence need not be particularly described, it'bcing' understood, however, that the plow and also" the-elevating-conveyer shown in said patent have been removed and that an elevating-com veyerprovided with ahopper at its receiving end has been substituted, so as to adapt the machine for receiving and conveying in accordance with my improvement. ing-conveyerA is arranged transversely to the length ofthe machine and preferably-extends the machine so that it will incline upwardly froni its receiving end, and it is also desirably made of such'length that its delivery end shall extend out from one side of the machine,

as shown in Fig. '1.

able frame aand an endless conveying belt .or apron (1 and like the clevating-conveyer in the patent referred to, it is desirably provided with guards aflsoas to form a passage-way whereof the upper leaf of the conveying belt or apron forms the bottom. This elevatingconveyer is provided at its recei ving end with r a hopper B, constituting a receiver into which the soil can bedepositcd from the elevating conveyor of another machine. The casing which forms the sides of this hopper is see ured to the frame of the elevating eonveyer, and to such end Fig; 6 illustrates the rear side 1) ol said casing secured to said frame oi. the eleval-i ng-conve yer by cleats or angle-iron a, which are understood to be bolted to the casing and frame. By such arraiigcmen the,

elevating-convcycr is practically PlOVlilL d at one end with a hopper or receiver. per has its bottom mainly formed by a couple Theelevat:

This hopof endless conveying belts or aprons b, which are so arranged that when they are caused to travel in the direction of the arrows in Fig. 6 they will eonve y the soil deposited in the hop per toward and deposit the same onto the endless belt a of the elevating-conveyer. By

. 75 The elevating-conveyor comprises a suitsuch arrangement a machine thus equipped can be driven alongside a machine provided both with an elevating-conve yer and a plow, as in said patent, so that durin g operation. the plowed-up soil will be first taken from the plow bythe elevatin g-conveyer of the machine thus furnished with. the plow and then discharged into the hopper B, from whence it will be taken by the conveyer-belt c of the elevat' ing-conveyer with which the second. machine is supplied. I

The comparatively short conveyerbel.ts I). can be arranged. at right angles to the line of belting a, as illustrated by the diagrammatic view, Fig. 3, or said belts b can be arranged obliquely to the line of belting (113.215 in Fir 6, in which'case any danger of long rods being caught by the corners of the-hopper will be avoided. i

The bottom of the hopper is of course open so that the two belts b and a portion of the belt of may form its bottonnend its back is also provided with a suitable opening I)", so as to. permit the soil and other matters deposited therein to be carried out by the conveyorbelt a.

The short conveyor-bolts b can be driven' from the belt-roll (J at the receiving end at the elevating-conveyor by means of link-belts, or by any other suitable gearing, the mode herein shown of operating the belts I) being to gear-connect short rotary shafts l) with the endsat' the belt-roll O, and connect sprockets upon said shaftssvith certain belt-rolls f orthe belts I) by link-belts E. The belt-r0ll C can be driven as in said patent or in any other shitable way.

From the foregoing it will be seen that the machine comprises an elevating-conveyor provided at one end with a receiver comprising a hoppencasing which is secured to a. frame a provided for the rolls of the belt c,/

and the short endless belts'or aprons I) which first receive the soil deposited in said hoppereffect a portion of the hopper-bottom, (see Fig, 6,) and by arranging the bolts 2') Z) at cpposite ei de's of the longitudinal middle portion of belt o the said bottom is practically extcndod, and furthermore, the oblong hoppercasi ng can be made much longer than the h'uspcn'ded in the patent hereinbot'ore referred to, and since the receiving ondoi' the said frame will be weighted by the hopper e sing and bolts 7) Z), a stay-chain a Fig. 7, can connect said casing with a drum or winding-rod a, which can be operated for the purpose of adjusting the length. of chain between the rod and hoppereasing with reference to the elevation of the receiving end oi the ole vatingbonveyer. With further reference to the receiving and cmiveying bolts '1). it is understood that they are positively operated during the progress of the machine by powertransmitting meanswhich is primarily operated by one oft-he wheels oi. the carriage, and that this application does not comprise the receiving and conveying belts operated solely by the weight of the material thereon, as embodied in application SerialNo. 399,8Q9 of myself and Clement l5. Ilinman.

What I claim as my invention is-- A machine for service in grading and ditching work, comprising a wheeled carriage, and an attachment supported from the-carriage and consisting of an elevating conveyor constructed with. belt'rollsand an endless conveying belt which is driven during the progress of the carriage, a hopper positioned at one side of the carriage and having at its bottom a receiving and conveying belt arr nged to discharge onto the conveying belt of the elevating conveyor, and gearing for driving the belt at the bottom of. the hopper from a belt roll of the elevating conveyor, substautially as described.
